The EdResearch for Action "Overview Series" summarizes the research on key topics to provide K-12 education decision makers and advocates with an evidence base to ground discussions about how to best serve students. This overview brief discusses what research shows about how student teaching experiences can best prepare new teachers. Effective student teaching experiences can address critical issues in the teacher workforce in the following ways: (1) increasing the effectiveness of novice teachers; (2) addressing teacher shortages and district needs; and (3) enhancing existing teacher workforce quality. The brief provides evidence-based practices and practices to avoid. [The University of Michigan's Marsal Family School of Education was one of the collaborators of this brief.]
